Thanks for the reply.

Wat betekent {\an8} zoals ({\an8}UIT MET MIJN MEID). Ik zou graag de betekenis weten. Kan dat weggelaten worden? Kan men dat verwijderen? Is dat nodig?

It is not only when I open the subtitle with any player it is even when I open it with subtitleworkshop or in notepad.
But anyway thanks for the answer?

how does it come that letters like these (é, è, ë, á .....) are given back as A@~~.
You can easily change that in subtitle workshop.
These letters are not properly given back on a player they are given back as A@=
when I post a subtitle the y are given back as they should.
